1 Corinthians 4:21

With a rod (en rabdwi). The so-called instrumental use of en like the Hebrew ( 1 Samuel 17:43 ). The shepherd leaned on his rod, staff, walking stick. The paedagogue had his rod also. Shall I come? (elqw;). Deliberative subjunctive. Paul gives them the choice. They can have him as their spiritual father or as their paedagogue with a rod.
